More familiarly, one uses 君 ‎(kun), especially of men, or ちゃん ‎(chan), especially of young women and children.

Referring to someone without using a suffix is quite rude, and is called 呼び捨て ‎(yobisute).

When used after a job name which refers to either the shop or the master depending on the context , it does not restrict animacy. For example, when referring to 床屋 (the barber shop or the hairdresser), both 床屋さんが一軒ある (inanimate ある) and 床屋さんが一人いる (animate いる) are correct.
